PROBLEM TO BE SOLVED: To provide a method for manufacturing electrostatic charge image developing toner, capable of stably manufacturing a toner having a smaller amount of pulverized particles with industrially high productivity by facilitating controlling of the particle shape, in a method for manufacturing the toner by a non-polymerization method. SOLUTION: The method for manufacturing the electrostatic charge image developing toner includes the processes of; granulating an aqueous dispersion liquid, including a kneaded material of toner raw materials by subjecting the kneaded material to high shearing at a velocity gradient of 50,000 to 100,000 sec<SP>-1</SP>generated by performing high-speed rotary shear stirring with a rotary shear stirring means of over 90 mm in the outside diameter of a turbine or rotor; performing operations to remove the aqueous dispersion liquid and/or a cleaning liquid under pressurization from the granulated substance, while vibrating a filter material within a cleaning chamber equipped with an impeller and the filter material a plurality number of times at the time of washing the granulated substance to obtain the toner from the cleaned granulated substance subjected repeatedly to washing.
